Enigmail is an add-on to the mail client of Mozilla Thunderbird and SeaMonkey allowing users to access the authentication and encryption features provided by GnuPG. Thus Enigmail enables Mozilla Thunderbird and SeaMonkey to send and receive digitally signed and/or encrypted messages using the OpenPGP standard.In order to provide the crypto-features, Enigmail requires GnuPG to be installed. We recommend GnuPG version 2.x since it provides gpg-agent. Minimum versions required are 1.4.9 or 2.0.9. If your operating system does not supply GnuPG by itself, you may download GnuPG for Windows or other systems. Main Features
